When the young man named Smith left Laurence's house after his interview with Richard he was slightly angry and not a little puzzled. The cause of his perplexity was the humorous lines round Richard's eyes and the cause of his anger was his failure to have noted them when first they met in the taxi and travelled home together on the Golders Green tube.

He had remarked on the peculiarity of this circumstance when he found Hipps and Van Diest in the dining room and had received no other comment than a snub from the American for his lack of observation.

These two gentlemen were in a state of exaggerated well being induced by enthusiasm over the capture they had made. Hipps was laying odds that after a course of treatment Anthony Barraclough would not only give away the secret but would breathe his first sweetheart's pet name. Van Diest was more concerned with details for the notation of the future radium company.

They appeared to regard the intrusion of Mr. Smith as a nuisance.

"Seems to me, gentlemen," he said, "there's something queer about the whole business. Barraclough was known to be starting tonight—and instead you succeed in laying him by the heels."

"What's wrong with that?"

"Nothing—except that it was all so infernally easy. Then again the fellow seems in such high spirits."

Van Diest wrinkled his forehead and nodded at this but Hipps waved it aside.

"Take it from me, he's in darn sight lower spirits than he wants us to think. Anthony's a sport and he'll sure pull the cucumber act as long as the cool weather lasts."

"You may be satisfied, gentlemen, but I'm not! You don't think he'd have given the information to anyone else."
